PreSonus Mixer/Amplifier Dials

I have a PreSonus HP60. The problem, is the seven distinct sections of the HP60 are not clearly separated. There is no spacing between each section, and all the dials are the same color. I decided to make new dials, with colors so that I can more easily manage the amplifier in a dark room.

I've included two different versions of the dials. One in full, and the other separated into two pieces, in case you want to make the line a different color. On my setup, I made the lines glow in the dark.
